Re: Curves workbench
Hi Chris,
The spiral curve is not parametrized by arc-length.
(I think it is parametrized by angle)
So you first need discretize and approximate the spiral, to get the arc-length parametrization.

Re: Curves workbench
I think you need to re-parameterize the spiral :
Curves|Join Curves
Curves|Discretize
Curves|Approximate Parameterization = Uniform
then the curve parameter will be uniform in length. (but from 0 to 1 - so the sketch need to be scaled somehow?)
EDIT: I see chrisG already got this - of course.

Re: Curves workbench
I have added a new tool : Flatten Face
It creates a parametric developed face from cylindrical and conical faces.
Only option is "InPlace" to put face on XY plane, or tangent to source face.

Thanks, this has been asked for quite often!

Re: Curves workbench
... it works with regular cones and cylinders.
Trying to generate an oblique cone/cylinder by pure placement of the top sketch001 => no result.
Only the cutting part should be oriented.
